DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

Referring to the drawings, reference numeral 10 generally designates aprinter, in accordance with the invention, for a conveyance, as defined.The printer 10 is intended for use in any suitable type of conveyance ofthe type described. However, for ease of reference, the printer 10 willbe described with reference to its application in a motor vehicle.

The printer 10 includes a chassis 12 (FIG. 4) covered by a top cover 16that has an access opening 18 closed off by a flap 20. The flap 20 isspring biased so that, when a cartridge 22 has been removed from theprinter 10, the flap is urged to the position shown in FIG. 1 of thedrawings.

It is important to note that the printer 10 does not have any of its owncontrols and, effectively, is a dumb unit. The unit is thereforeactuated from a device from which it is desired to print material.

The device that sends commands to the printer 10 can either be hardwired to the printer 10, for example, via a wiring loom of the motorvehicle or, instead, the device may send commands to the printer 10 in awireless manner. For this purpose, the printer 10 includes a port 24able to detect wireless communications of some form.

Various forms of wireless communications can be employed such as aninfra red communication system, a personal area network (PAN) systemreferred to as Bluetooth, a radio local area network (LAN) or a digitalcordless telephone system.

Further, the device which communicates with the printer 10 can be ofvarious forms such as, for example, a palm computer, a laptop computer,a mobile telephone, a digital camera, a scanner, a diagnostics systemfor the motor vehicle, a navigation system, a vehicle entertainmentsystem, or the like. This is not intended to be an exhaustive list andthose skilled in the art will readily conceive of other devices that cancommunicate with the printer 10.

The port 24 is mounted on a front face 26 of the printer 10. As shown ingreater detail in FIG. 2 of the drawings, a rear face 28 of the printer10 accommodates a data socket 30 and a power socket 32. It will beappreciated that, when the printer 10 communicates exclusively in awireless manner, the data socket 30 may be omitted.

The printer 10 incorporates a printhead 34 (FIG. 4). The printhead 34 isa pagewidth inkjet printhead. More particularly, the printhead 34 is afour color printhead, or three color plus infrared ink, printhead thatprints photo quality prints on print media stored in the cartridge 22.The printhead 34 comprises an array of nozzles to provide printing at1600 dpi. The nozzles of the printhead 34 are manufactured using theapplicant's Memjet technology.

The printhead 34 receives commands from a printed circuit board (PCB) 36secured to the chassis 12.

A pair of drive motors 38 and 40 is mounted on a sidewall 42 of thechassis 12. The drive motor 38, which is in the form of a stepper motor,drives a first drive arrangement in the form of a first gear train 44.The first gear train 44 is mounted on a side molding 46 of the chassis12.

The drive motor 40, which is also in the form of a stepper motor, drivesa drive roller 48 via a second drive arrangement. The second drivearrangement comprises a second gear train 50.

The printhead 34 receives ink from ink hoses 52 that communicate with anink supply reservoir 54 (FIGS. 13 and 15) of the cartridge 22 via an inksupply manifold 56, as will be described in greater detail below.

Referring to FIG. 5 of the drawings, an exploded view of the printer 10is illustrated. It is to be noted that the printhead 34 communicateswith the PCB 36 via a TAB film 54.

A slot 58 is defined in the side molding 46. The slot 58 receives acorresponding formation of the cartridge 22 in it. Further, a roller set60 is mounted on a base 62 of the printer 10. The roller set 60comprises a rotatable axle 62. A cog 64 is mounted proximate each end ofthe axle 62. Each cog 64 engages a rack 100, 102 (FIG. 12) on thecartridge 22 for inhibiting skewing of the cartridge 22 as it isinserted into, or withdrawn from, the interior of the printer 10.

The first gear train 44 engages a pick up roller 68 of the printer 10.The pick up roller 68 picks up print media in the form of a sheet ofpaper from a stack 70 of paper (FIG. 13) in the cartridge 22 for feedingto the printhead 34 of the printer 10 when printing is to be effected.

As shown in greater detail in FIG. 9 of the drawings, the first geartrain 44 is powered by the stepper motor 38 via an axle 72 extendingacross the printer 10 to convey power from the stepper motor 38 to thefirst gear train 44. A gear 74 is mounted against the molding 46 at oneend of the axle 72. The gear 74 drives a reduction gear set 76. Further,the reduction gear set 76 communicates with a reversing mechanism 78.Accordingly, the gear train 44 performs two functions. When thereversing mechanism 78 is not selected, the gear train 44 engages anupper rack 80 on the cartridge 22 for feeding the cartridge 22 into theprinter 10 or ejecting the cartridge 22 from the printer 10. Instead,when the reversing mechanism is in the position shown in FIG. 9 of thedrawings, it engages the pick up roller 68 or, more particularly, a gear82 mounted at an end of the pick up roller 68. The gear train 44 thenserves to feed the paper to the drive roller 48 for conveying to theprinthead 34.

Referring now to FIGS. 11 to 20 of the drawings, the cartridge 22 isdescribed in greater detail.

The cartridge 22 comprises a base molding 90. The base molding 90 isclosed off by a metal cover 92. The cover 92 has a pair of transverselyspaced openings 94 defined in a front edge thereof. These openings 94permit the pick up roller 68 of the printer 10 to engage a topmost sheetof the stack 70 of paper within the cartridge 22.

A toothed rack 96 is provided on one side of the cartridge 22. Thetoothed rack 96 defines the upper rack 80 that is engaged by a gear ofthe first gear train 44 for insertion of the cartridge 22 into, or itsejection from, the printer 10. A rib 98 extends longitudinally along theside of the toothed rack 96. The rib 98 is received in the slot 58 inthe side molding 46 of the printer 10. A lower surface of the toothedrack 96 also has the rack 100 (FIG. 12) for engagement with one of thecogs 64. An opposed side of the base molding 90 of the cartridge 22carries the other rack 102 that engages the other cog 64 for inhibitingskewing of the cartridge 22 when it is inserted into, or ejected from,the printer 10.

A feed slot 104 is defined at a front edge of the metal cover throughwhich a sheet of paper to be printed is passed in use. The feed slot 104is partially defined by a plastics strip 106, which inhibits more thanone sheet of paper being fed to the printhead 34 at any one time.

A transversely extending trough 108 is defined outwardly of the strip106. The trough 108 accommodates a sprung roller 110 therein. The roller110 is supported in the trough 108 via a plurality of clips 112.

The roller 110 is biased upwardly relative to a base of the trough 108via a plurality of leaf springs 114. The leaf springs 114 are formedintegrally with an L-shaped metal bracket 116 that partially forms thetrough 108. The roller 110 is a snap-fit in the clips 112.

A platen 118 is accommodated in the base molding 90. The platen 118 isspring biased via a plurality of leaf springs 120 which engage a floor122 of the base molding 90 for urging the stack 70 of paper against thecover 92.

The ink supply reservoir 54 includes an ink supply molding 124 formedintegrally with the base molding 90. The ink supply molding 124 definesa plurality of ink supply channels 126. Each ink supply channel 126contains a particular color of ink. In this context, the term “color” isto be understood as including inks which are invisible in the visiblespectrum such as, for example, infra red inks.

The channels 126 are closed off by a flexible bladder-like membrane 128,which is heat-sealed to the molding 124. It will be appreciated that, asink is withdrawn from each channel 126, the associated membrane 128collapses into the channel 126 thereby inhibiting the ingress of airinto that channel 126.

Each channel 126 communicates with an ink outlet 130. Each ink outlet130 is in the form of a rupturable seal.

As shown in greater detail in FIG. 5 of the drawings, the ink supplymanifold 56 of the printer 10 includes pins 132. These pins 132communicate with the ink supply hoses 52. When the cartridge 22 isinserted into the printer 10, and the cartridge 22 is driven home by thegear train 44, the pins 132 pierce the seals 130 to place the hoses 52in communication with their associated ink supply channels 126.

The cartridge 22 includes a quality assurance chip 134. This chip 134ensures correct communications between the cartridge 22 and the printer10 and that the cartridge 22 is of the required quality. The chip 134communicates with the printer 10 via chip contacts 136 mounted on theink supply manifold 56 of the printer 10. Thus, when the cartridge 22 isdriven home by the gear train 44, the chip 134 engages the contacts 136for enabling communications to be established between the chip 134 andthe circuit board 36 of the printer 10.

FIG. 17 shows a first embodiment of the cartridge 22 with the ink supplyreservoir 54 arranged on a left side of the cartridge 22 and the stack70 arranged on the right side of the cartridge 22.

FIG. 18 shows another embodiment of the cartridge 22 with the stack 70arranged on the left side of the cartridge 22 and the ink supplyreservoir 54 being arranged on the right side of the cartridge 22.

FIG. 19 shows yet a further embodiment with the stack 70 arranged at afront of the cartridge 22 with the ink supply reservoir 54 beingarranged at a rear of the cartridge 22.

FIG. 20 shows yet a further embodiment with the stack 70 arranged on theplaten 118 with the ink supply reservoir 54 being arranged below theplaten 118. It will be appreciated also, with reference to thisembodiment that the ink supply reservoir 54 could be arranged above thestack of paper 70 although this will increase the height of thecartridge 22 and, accordingly, the height of the printer 10.

The cartridge 22 is a disposable unit so that, once its ink supply andpaper supply have been depleted, the cartridge is disposed of. Instead,the cartridge 22 may be re-useable. In the latter case, once the supplyof ink and paper in the cartridge 22 have been depleted and thecartridge 22 is ejected from the printer 10, the used, empty cartridge22 can be taken by a user to a supplier for a refund. It is to be notedthat the cartridge 22 is automatically ejected from the printer 10 onceits supply of paper and/or ink has been depleted.

As described above, the printer 10 is intended particularly for use in amotor vehicle. The printer 10 is dimensioned to fit in numerouspositions in a passenger compartment 130 (FIG. 21) of a motor vehicle132. The printer 10 is, desirably, mounted where it is readilyaccessible within the passenger compartment 130 of the vehicle 132.

Various desirable locations within the passenger compartment 130 are nowdescribed. Firstly, a printer, designated by the reference numeral 10.1,can be mounted in a dashboard 134 of the vehicle 132. This provides agood location at least for front occupants of the passenger compartment130 and, usually, this part of the dashboard 134 of the vehicle 132 isunoccupied by other equipment.

A second desirable location is in an overhead fitting 136 arranged abovea rear view mirror 138 of the passenger compartment 130. Thus, a printer10.2 can be mounted in this fitting 136. Once again, this provides goodaccess, at least for front occupants of the passenger compartment.

Another location in the passenger compartment for a printer 10.3 is aglovebox 140. This is a convenient location in that the printer 10.3 canbe built into the lid 140 of the glovebox. This renders the printer 10.3readily accessible for servicing purposes.

Yet a further location is in an upper region of a console 142 asillustrated by printer 10.4. Another suitable location for a printer10.5 is in a lower region of the console 142 where, for example, cointrays or the like are sometimes mounted. A further suitable location isin a central armrest 144 of the passenger compartment 130 in which aprinter 10.6 could be installed. Still further, if there is sufficientspace, printers 10.7 could be built into door arm rests 146 of thepassenger compartment. Only the person adjacent such a door armrest willhave easy access to the printer 10.7 but this need not necessarily be amajor inconvenience.

It will also be appreciated that more than one printer could be providedin the passenger compartment. Although not shown, printers could also beprovided in back rests of the front seats of the passenger compartment130.

Those skilled in the art will appreciate that the exemplified locationsas described above are not the only locations in which printers 10 couldbe installed and it is conceivable that printers could be stored in lessconvenient location such as in footwells of the passenger compartment130, under the front seats, in an arm rest of a rear seat of thepassenger compartment 130, or the like.

Also, it is envisaged that receiving sockets for printers could bemolded into relevant fittings in the passenger compartment 130 duringmanufacture of the vehicle 132. The receiving sockets could includewiring for the printer 10. The receiving sockets could then be closedoff by blanking plates, the relevant blanking plate being removed tofacilitate installation of the printer 10.

In another embodiment of the invention, the printers 10 are built intoand form part of car audio devices, which are also referred to as in carentertainment (ICE) units.

Accordingly, as shown in FIG. 22 of the drawings, an ICE unit 150 isillustrated. The ICE unit 150 incorporates a radio having an LCD display152, a CD player having a slot 154 in a front panel of the unit 150 andvarious controls 158.

The ICE unit 150 includes a printer 10 as described above including thecartridge 22. The ICE unit 150 includes controls 160 for controllingprinting from the printer 10. The controls 160 are used for instructingthe printer 10 to print required information. Depending on the materialto be printed, the LCD 152 can be used for previewing material to beprinted.

It is envisaged that this embodiment of the invention will be used forprinting information from radio broadcasts, CD's played in the CD player150, or the like.

Referring now FIG. 23 of the drawings a variation of the ICE unit 150illustrated in FIG. 22 is illustrated. With reference to FIG. 22, likereference numerals refer to like parts, unless otherwise specified.

In this embodiment of the invention, the ICE unit 150 includes a slot162 in which a digital camera 164 is received. The digital camera 164and the slot 162 have corresponding electrical contacts so thatinformation can be downloaded from the camera 164 to be printed via theprinter 10. Accordingly, it is an advantage of this embodiment of theinvention that information from a digital camera can be downloaded assoon as a user of the camera has used the camera and/or has returned tothe vehicle 132. Thus, the user need not, unlike at present, await theuser's return to a venue where the camera can communicate with acomputer for downloading information captured by the camera 164.

It is also contemplated that a suitable slot 162 could be incorporatedin, for example, the dashboard 134 of the vehicle 132 as illustrated at166 so that a camera can be incorporated in the vehicle 132 for printingon any one of the printers 10.1 to 10.7. In other words, the slot 166need not form part of an ICE unit but may be provided as a separatefeature in the vehicle 132 in association with one of the printers 10.1to 10.7.

Referring now to FIGS. 24 and 25 of the drawings, a further ICE unit 170is provided. In this embodiment, the ICE unit 170, in addition to a CDplayer 172 and a radio having controls 174, includes a full color LCD176. The ICE unit 170 further functions as a satellite navigation unitand may also be used for receiving television signals. The unit 170incorporates a printer 10 of the type described above. The unit 170includes controls 178. These controls 178 are GPS controls and are usedfor satellite navigation purposes. In addition, a further bank ofcontrols 180 is provided for controlling the printer 10.

With this unit 170, a map, or the like, can be downloaded and printedvia the printer 10 or images from the LCD 176 when it is used as atelevision receiver can be printed via the printer 10.

The unit 170 shown in FIG. 25 of the drawings, once again, incorporatesa slot 182 for receiving a digital camera 184. The slot 182 and thedigital camera 184 therefore have corresponding electrical contacts forenabling data to be downloaded from the digital camera 184 to be printedon the printer 10.

Accordingly, it is an advantage of the invention that an in-vehicleprinter 10 is provided for enabling suitable materials to be downloadedand printed rapidly. Further, the fact that the printhead 34 of theprinter 10 uses a pagewidth, full color printhead means that highquality images can be printed using the printer 10. It will also beappreciated that, due to the fact that the printhead 34 is a pagewidthprinthead and does not traverse the media on which an image is beingprinted, it is less susceptible to jolting, bumping or other suchdisturbances. In other words, it is less likely to produce a poorquality image even if printing is taking place while the vehicle ismoving.

Although the invention has been described with reference to a number orspecific embodiments, it will be appreciated by those skilled in the artthat the invention can be embodied in many other forms.
